On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0022] It should be understood that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. In addition, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. As used herein the terms "vertical", "horizontal", "left", "right" and the like are used for explanation purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] Referring to Figure 1 The adjustable pipeline connecting piece in the application comprises a pipe body 10 and a movable sleeve 20 sleeved on the pipe body 10, one end of the pipe body 10 is provided with a first connecting part for connecting a pipe material, the other end is provided with a limiting part, and the movable sleeve 20 can slide along the axial direction of the pipe body 10 between the first connecting part and the limiting part.

[0025] One end of the movable sleeve 20 is provided with a sealing part for sealing the gap between the movable sleeve 20 and the pipe body 10, and the other end is provided with a second connecting part for connecting a pipe material.

[0026] The pipe body 10 and the movable sleeve 20 for connecting a pipe material are telescopic in the axial direction, so that when installed, the reserved gap between the pipe materials can be effectively adapted, the versatility and flexibility of the pipeline connecting piece are greatly improved, and a more convenient and efficient solution is provided for the pipeline connecting project.

[0027] Specifically, the first connecting part comprises a first nut 31 rotatably connected to the pipe body 10, and one end of the pipe body 10 is provided with a limiting step 32 for limiting the first nut 31. It can be understood that the first nut 31 is used for cooperating with the pipe material, so that one end of the pipe material is tightly fitted on the end face of the limiting step 32. Further, in order to ensure the sealing performance of the cooperation between the pipe material and the limiting step 32, a sealing gasket (not shown in the figure) can also be arranged on the end face of the limiting step 32 in this embodiment, so as to increase the sealing effect of the butt joint between the pipe material and the pipe body 10.

[0028] Specifically, the limiting component includes a clamping groove 41 arranged on the outer wall of the pipe body 10, and a clamping spring 42 clamped in the clamping groove 41. It can be understood that when the movable sleeve 20 is sleeved into the pipe body 10, the clamping spring 42 is clamped into the clamping groove 41, the limiting of the movable sleeve 20 is realized, and it is ensured that the movable sleeve 20 can slide within a predetermined range without being separated from the pipe body 10.

[0029] Specifically, the sealing component includes a second screw cap 51 and a sealing ring 52. The second screw cap 51 is threadedly connected to one end of the movable sleeve 20. The sealing ring 52 is arranged in a space formed by the second screw cap 51, the movable sleeve 20 and the pipe body 10. In actual application, the user can extrude the sealing ring 52 by rotating the second screw cap 51, so that the sealing ring 52 tightly fits the gap between the movable sleeve 20 and the pipe body 10, and the sealing between the movable sleeve 20 and the pipe body 10 is realized.

[0030] Further, an end face of one end of the movable sleeve 20 towards the sealing ring 52 is provided as a bevel 53, and the bevel 53 and the outer wall of the pipe body 10 form a gap for accommodating the sealing ring 52. The design of the bevel 53 enables the sealing ring 52 to be extruded into the gap under the guidance of the bevel 53 after being extruded by the second screw cap 51, so that the sealing ring 52 is better filled into the gap between the movable sleeve 20 and the pipe body 10, the dead angle of sealing is reduced, and the sealing effect is further improved.

[0031] Specifically, the second connecting part is an external thread 60 arranged on the outer wall of the movable sleeve 20. The external thread 60 is used for connecting a pipe with a standard internal thread. Further, the external thread 60 is provided with a lock cap 70. The lock cap 70 is used for abutting against the end face of the pipe, and can provide additional axial pressure after being tightened, so as to further fasten the connection between the pipe and the movable sleeve 20. The additional fastening effect effectively prevents the pipe and the external thread 60 from gradually loosening due to vibration and the like during long-term cooperation, ensures the stability and reliability of the connection, and reduces the risk of leakage or system failure caused by loosening of the connection.

[0032] Further, the outer wall of the movable sleeve 20 is provided with a wrench position 80. The design of the wrench position 80 facilitates the use of a wrench by an assembler to rotate the movable sleeve 20, and improves the efficiency of pipeline assembly.
